RDS on pistols

Care to share any negative experiences you have (implied with the use of the ellipsis) with the MOS?

My experience with it has been great so far. There have been no malfunctions in the several hundred rounds I've put through it so far.

It's an engineering failure. It will not hold up to any hard use. They milled it too deep and the use of the mounting plate lends itself to being a weakness. The sights are pointless since the RDS sits higher than it should, so you have to buy different BUIS. Why on earth would they even sell it like that. It just seems like they made a half ass attempt to get into the RDS business.

How deep is the average aftermarket milled area? Do they mill in shear lugs?
You got me curious enough to want to run some calculations on it.

I have an ATEI milled Glock running an RMR 06. Mine has shear lugs milled into it and the slot the RMR fits into is cut specifically for that particular RMR. The slot is tight enough that it almost pops into and out of place. There is no wobble at all if the screws are loose, which indicates that the screws are only there to keep the optic attached to the slide under recoil.

I would guess that is standard for any ATEI gun though.

Yup. This is how my two ATEi'ed guns are. I have finish scraped off one of the RMRs where I was changing the battery and didn't put it back into the milled recess perfectly straight and the edge of the slide cut scraped finish off the RMR. Very tight fit.

Tact, how much trigger time do you have on a MOS model? I don't understand your comment on the sight sitting too high and requiring different sights. Any slide with a RMR milled into it requires suppressor height sights.

Referencing the above images, I believe he's saying A) the optic sits higher on the MOS than on a milled slide, and B) the MOS, which is sold as an optic-ready model, inexplicably does not come with the suppressor height sights required for use with an optic from the factory.

What Whootsinator said....and even regular suppressor sights are too low. To get a cowitness you have to buy MOS specific sights.....they are even taller than regular supressor sights.

Basically it costs like $125 on average to get a slide milled and done correctly. How much extra does an MOS cost?

On the G19 MOS...
...The measurement from top of the slide to the top of the rear section of the RMR I am measuring 0.2750-inch. So, if you want a cowitness (I do not), you will need sights designed for the MOS.

...The total milled area (without an adaptor plate) is 0.1960-inch deep by 1.9290-inch long. The adaptor plate is about 0.1000-inch deep.

And that .100 plate is what you mount your RMR to..... that's like 3 threads of the screw maybe. Hey, as long as your happy with it. You don't have to justify your purchase to me. All I did was wish you good luck at the beginning.
 
Update from Trijicon; They are filling December 2015 Orders now, and should be moving into January 2016 orders soon. They are working on creating a second shift for RMR's and night sights due to the long backorder log. I've been waiting 10 weeks and counting through Pro-Motive.

Not to beat a dead horse here, but I'm looking into doing this later this year, and the RMR06 is still the favorite? I was originally looking at the dual illuminated model but all my research is saying that the dot washout seems to be a major issue with those?

Has anybody with astigmatism used a rm09 and not found the dot to be to small?

Now that Dawson is making sights for the MOS model I'm considering buying one. I remember reading something about the glock screws for the rmr were not that robust and they recommended buying trijicon screws.
Does anybody have any extended range time with the mos model that can comment on the quality of the MOS mounting system?

Pat, I have astigmatism, and I have both an RM06 and an RM09. Honesty with my eyes, I can't even tell a difference. I have just adjusted the dot until it is bright enough to be readily seen, but not bloom too bad on me (which always happens to some degree). I had planned ont he RM09 going on a carbine, but in the meantime, I have compared it to my 3.5 dot, and they both work the same for me as far as how they look.

I agree, been running a G19/RM06 and a G17/T-1 (4 MOA), got a chance to play with a friends RM09 and quite frankly the Aimpoint dot looks the smallest. Must depend on the particular astigmatism.

Don't use the Glock screws for anything other than attaching the adapter plate to the slide. You need to use the Trijicon RMR Mounting Kit (Trijicon P/N: AC32064) to attach the RMR to the MOS plate. After that it is all just installing per OEM instructions.

I have put several hundred rounds through my G19MOS without any issues. I also decided to run some numbers on the screws and threaded plates. Everything looked good so I'm more than satisfied, but I will monitor it for fatigue issues over the long-term usage.

I agree. Everyone has unique vision, and especially with astigmatism, what you see with a dot can vary greatly.

Some of you may remember TLG's "grey" back-up gun from the 2012-2013 9 mm SA/Warren 1911 endurance test, as noted in these older posts: https://pistol-forum.com/showthread....field-9mm-1911 and http://pistol-training.com/archives/6936. Recently that pistol had an RMR06 added to it thanks to Mark Housel at L&M Precision: http://www.landmprecisiongunworks.com/.

Despite the new RDS, the pistol has functioned flawlessly over the first few hundred rounds of typical 147 gr ammunition. Accuracy is quite acceptable, as shown in the target below, which was recorded during the initial RDS zeroing--I suspect the pistol is capable of better group sizes once the sight is fully dialed in:

During the 25 years I primarily carried a .45 Auto 1911, all my personally owned pistols had iron sights, flat mainspring housings, and long triggers. Since transitioning to only using RDS equipped pistols, I have noted that RDS equipped 1911's point and shoot much better for me when using an arched mainspring housing and short triggers--I suspect those will be added to this pistol in the near future, much like with the 1911 below:
